Benefits of technology

The patent describes a way to establish a virtual private network connection between a client device and a core network through a network interface device. This device monitors the mobile backhaul of the core network and identifies an access request from a client device to establish a VPN connection. The device then performs address translation and performs low latency VPN forwarding without needing additional administrative actions. The device can also update a look-up table to easily discover and connect users with the same VPN. The technical effect of this patent is the ability to quickly and efficiently establish a secure and low-latency VPN connection through a network interface device.

Problems solved by technology

Using customer equipment for the establishment of a VPN connection might result in low latency, however the deployment of the customer equipment is not always possible.
However, there might be situations when machine to machine (M2M) interaction might need low latency communication while subjects are belonging to different MNOs.

first embodiment

[0031]FIG. 1 illustrates a system 1 for facilitating the establishment of a virtual private network in a cellular communication network according to a

[0032]As can be seen in FIG. 1, a given geographical area is subdivided into a number of smaller radio coverage areas, the core network portions 2, 3, to define the cellular communication network. Further, each core network portion is provided with a base radio station, in particular an antenna 4, 5.

[0033]There are further shown two client devices 6, 7, which might try to communicate with each other or the Internet 8, for example an enterprise network.

[0034]One mechanism to achieve this is the establishment of a virtual private network (VPN) connection.

[0035]A VPN extends a private network across a public network, such as the Internet. It enables a computer to send and receive data across shared or public networks as if it is directly connected to the private network, while benefiting from the functionality, security and management pol...

second embodiment

[0038]FIG. 2 illustrates a network interface device 10 of a system for facilitating the establishment of a virtual private network in a cellular communication network according to a

[0039]According to the embodiment shown in FIG. 2, the network interface device 10 comprises an identifying means 11 for identifying an access request from a client device to establish a VPN connection through a core network portion, a determining means 12 for determining an application information from the client device, a comparing means 13 for comparing the application information to a network information of the core network portion to determine whether the application information matches the network information, a first connection means 14 for establishing a VPN connection of the client device through the core network portion using the application information if the application information matches the network information, a translation means 15 for translating the application information into an infor...

third embodiment

[0046]FIG. 3 illustrates a flow chart of a method 30 for facilitating the establishment of a virtual private network in a cellular communication network according to a

[0047]In particular, FIG. 3 illustrates a method 30 for facilitating the establishment of a virtual private network in a cellular communication network, wherein the cellular communication network comprises a plurality of core network portions and a plurality of antennas. Each antenna is associated with a core network portion. The method comprises the steps of arranging a network interface in close proximity to the plurality of antennas 31, identifying an access request from a client device to establish a virtual private network connection through a core network portion by means of the network interface device 32, determining application information from the client device by means of the network interface device 33 and comparing the application information to a network information of the core network portion to determin...
